Abstract
The invention discloses a formula and a process of a butyl rubber film-covered gasket for detection. The butyl rubber film-covered gasket is prepared from the following components in parts by weight: 100 parts of brominated butyl rubber, 85-95 parts of kaoline, 0.1 part of carbon black, 3 parts of titanium dioxide, 5-6 parts of PH value regulator and 0.1-0.3 part of sulfur. The process comprises the following production steps: step 1, dosing; step 2, rubber mixing; step 3, pre-molding; step 4, primary vulcanization; step 5, secondary vulcanization; step 6, edge removal; step 7, cleaning. On the basis of the traditional technique, the formula and the process of the rubber gasket are improved, and the surface of the rubber gasket is covered with a layer of inert film material to prevent the chemical reaction between the gasket and drugs, and therefore, the stability of a standard substance for detection is enhanced.
Description
Technical field
The present invention relates to a kind of formula and technique of rubber sheet gasket, particularly relate to a kind of formula and the technique that detect use isoprene-isobutylene rubber overlay film pad.
Background technology
Detection isoprene-isobutylene rubber pad is formed by design for rubber formulation, directly contacts with testing standard product.It has unstable and the formula constituent complicacy of conventional polymer material, therefore, can by form and medicine generation chemical reactions such as absorption, absorption, infiltration, migrations, the result of these chemical reactions directly affects the stability of detection standard substance.Therefore, those skilled in the art needs a kind of new technical scheme badly and solves this problem.
Summary of the invention
Invent problem to be solved to be: provide a kind of and detect formula with isoprene-isobutylene rubber overlay film pad and technique, it has and prevents pad and medicine generation chemical reaction, the feature of the stability of enhancing detection standard substance.
Technical solution problem of the present invention adopts following technical scheme:
Detect the formula with isoprene-isobutylene rubber overlay film pad, be made up of by weight following component: brominated butyl rubber 100 parts, kaolin 85-95 part, carbon black 0.1 part, titanium dioxide 3 parts, pH value conditioning agent 5-6 part, sulphur 0.1-0.3 part.
Preferably, described pH value conditioning agent is activated magnesia.
Detect the technique with isoprene-isobutylene rubber overlay film pad, comprise following production stage:
Step one, by formula carry out various material preparation and put into the barrel of specifying, i.e. blending process;
Step 2, evenly mixing by material various in barrel, obtain sizing material, i.e. mixing process;
Step 3, as requested sizing material is made the film being convenient to sulfuration specified dimension weight, i.e. preform process;
Step 4, the film of the specified dimension weight made is put into mould do a sulfuration, i.e. a sulfidation;
After step 5, a sulfuration die sinking, film does not take out, and is directly placed on by mould material on film and carries out post cure, i.e. secondary sulfurizing course;
Step 6, through die-cut formation finished product, namely except crack approach;
Step 7, employing automatically cleaning clean rubber cushion, i.e. cleaning process;
Preferably, described mould material is the ETFE film of thickness 4mil.
The invention has the beneficial effects as follows: the present invention is on the basis of conventional art, improve the composition and engineering of rubber sheet gasket, and cover one deck inert coating material on the surface of rubber sheet gasket, prevent pad and medicine generation chemical reaction, strengthen the stability of detection standard substance.
